Map explanation

The map below shows the location of 6,690 GP surgeries in England. The full list (March 2020) contains 6,801 surgeries but 111 of these have data missing and are not included in the map.

Each surgery is colour-coded according to the number of people aged 65+ on its register (purple means the surgery is in the top or “oldest” quintile (20%) of surgeries by age; yellow means it is one of the 20% “youngest” (least people aged 65+)).

The circle representing each surgery is also sized according to the total number of patients registered there (larger means more patients).

Finally, the map is made up of two layers, which may be switched on and off using the layers feature on the left of the map. One layer contains those surgeries where more than 30% of patients are registered for one of three online services (making appointments, ordering repeat prescriptions, looking up personal details) - this is 2,770 surgeries (41%). The other layer shows those where less than 30% of patients are registered for the available online services (3,920, or 59% of surgeries).

Data on availability and use of online services is from the NHS England website, dated January 2020.
